Structural and Parameter Optimization of Well Gauges for Chip Carrying Performance Study
Aiming to address the issue of the limited effectiveness of rock chips passing through the well gauge during the integrated wellbore preparation operation,which results in a reduced chip-carrying capacity of the well gauge,a structural optimization design of the well gauge was implemented through the use of an orthogonal test method,with the chip-carrying capacity serving as the performance index,and the optimal structural parameters were identified.The following parameters were obtained:the depth of the flow-through channel is 6 mm,the helix angle of the flow-through channel is 80°,the width of the flow-through channel is 40 mm,and the cone angle of the correcting sleeve is 11°.Furthermore,the optimal structural parameters were optimized and selected for the well gauge.In addition,the optimal structural parameters were employed to optimize the operating parameters of the well gauge,resulting in the selection of the optimal operating parameters:a circulating displacement of 1.1 m3/min and a rotational speed of 60 r/min.The results of the study demonstrate that the optimization of the structural parameters of the well gauge and the optimal selection of the operating parameters enhance the chip-carrying capacity of the well gauge,thereby providing a reference point for the optimization of the structural parameters of the well gauge and the operating parameters of the well gauge,which is of significant guidance and reference value.
